2009 Annual Report

1a. Objectives (from AD-416)
This is a Standard Research and Extension Project (SREPs) bringing together scientists, economists, extension and industries in Hawaii and Oregon to: 1) investigate the potential of 'ohelo (Vaccinium reticulatum) an endemic Hawaiian berry as an ornamental potted plant, 2) establish sustainable 'ohelo berry production in Hawaii for culinary and value added products, 3) conduct critical economical analysis for objectives 1 & 2, 4) identify epidemiology, biology, host-pathogen interactions and management of potential fungal diseases that may impact sustainability.

1b. Approach (from AD-416)
Develop clonal production protocols for three selected ornamental clones through cuttings and tissue culture propagation; grow out evaluation at four elevations. Develop sustainable berry production using 'ohelo seedlings at four sites. Prepare feasibility analyses of 'ohelo as an ornamental and berry crop. Develop culinary and value added uses for 'Ohelo berries. Determine the etiology and management of fungal diseases of 'ohelo in Hawaii. Extension and technology transfer to stakeholders. Documents Reimbursable with CSREES. Log 37102.

3. Progress Report
Selected clonal ohelo accessions were distributed to Oregon cooperators for mass propagation, long-term storage and finger-printing studies; discussions on patenting of selected clones continues; field and nursery plantings for the ornamental and fruit productions are in place at four sites (Volcano, Lalamilo, Mealani and Kona), workshop of nursery production and plant material distribution to the nurseryman association cooperator for July, 2009, and a potential public release date in 2010 has been targeted. Fruit samples were provided to an industry partner last fall for research in product development, and will continue to provide fruits samples as fruits become available; observation data on flowering, fruiting and shoot regeneration in relation to pruning and fertilizer application are being gathered. The ADODR monitored progress through field visits, meeting with employees responsible for the oversight of the plantings, e mail and telephone calls with all cooperators, discussing project plans, reviewing program goals and accomplishments with the cooperators, stakeholders meetings.
